HIV-2 gp36, His/重组艾滋病毒2 gp36,His Tag
产品编号:HIV-151
产品规格:100μg/500μg/1mg
Introduction HIV-1 and HIV-2 appear to package their RNA differently. HIV-1 binds to any appropriate RNA whereas HIV-2 preferentially binds to mRNA which creates the Gag protein itself. This means that HIV-1 is better able to mutate. HIV-2 is transmitted in the same ways as HIV-1: Through exposure to bodily fluids such as blood, semen, tears and vaginal fluids. Immunodeficiency develops more slowly with HIV-2.
HIV-2 is less infectious in the early stages of the virus than with HIV-1.
The infectiousness of HIV-2 increases as the virus progresses.
Major differences include reduced pathogenicity of HIV-2 relative to HIV-1, enhanced immune control of HIV-2 infection and often some degree of CD4-independence. Despite considerable sequence and phenotypic differences between HIV-1 and 2 envelopes, structurally they are quite similar. Both membrane-anchored proteins eventually form the 6-helix bundles from the N-terminal and C-terminal regions of the ectodomain, which is common to many viral and cellular fusion proteins and which seems to drive fusion. HIV-1 gp41 helical regions can form more stable 6-helix bundles than HIV-2 gp41 helical regions however HIV-2 fusion occurs at a lower threshold temperature (25°C), does not require Ca2+ in the medium, is insensitive to treatment of target cells with cytochalasin B, and is not affected by target membrane glycosphingolipid composition. Description HIV-2 gp36 His tag recombinant- is a 64 kDa protein and contains the sequence of HIV-2 envelope immunodominant regions gp36 having a 6X His tag / chaperone protein on the N-terminus. Source Escherichia Coli. Physical Appearance Sterile filtered colorless clear solution. Formulation 20mM sodium carbonate pH-9.6 & 0.02% sodium azide. Purity Greater than 95.0% as determined by HPLC analysis and SDS-PAGE. Stability HIV-2 gp36 protein is shipped at ambient temperature. Upon arrival, Store at -20°C. Stable for Five years frozen. One month in solution at room temperature. Specificity Immunoreactive with all sera of HIV-2 infected individuals. Applications HIV-2 gp36 antigen is suitable for ELISA and Western blots, excellent antigen for early detection of HIV seroconvertors with minimal specificity problems. Usage ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
